matlab粗糙集算法，主要使用于神经网络和支持向量机等算法的预处理，可以有效地筛选数据(matlab rough set algorithm, mainly used in the pre-processing of the neural network and support vector machine algorithm can effectively filter the data)

说明：  对雷达射频端实施射频噪声干扰，观测雷达目标回波干扰情况。给出了具体的matlab源码，和效果图。(Radio frequency noise jamming is applied to the radio frequency end of the radar, and radar target echo jamming is observed. The specific matlab source code and the effect diagram are given.)

Drop fall algorithm used to segmentate digits

求解线性矩阵不等式的程序，简单明了，有注释，对于学习LMI有很好的帮助(Procedures for solving linear matrix inequalities, simple and clear, with annotations, very good for learning with the help of LMI)

说明：  Lorenz 系统利用龙格库塔来用Matlab编程(Lorenz system using Runge-Kutta to use the Matlab programming)

说明：  广义互相关函数，包含所有互相关的权函数，可以方便的使用它，其中PHAT加权效果最好！(Generalized cross-correlation function, contains all of the right to cross-correlation function, can easily use it, in which the weighted best PHAT!)

matlab 代码，主要用于计算一数据矩阵的标准差，方差，变异系数，话三维曲面图(matlab code, data matrix used to calculate a standard deviation, variance, coefficient of variation, then D surface chart)
